How to apply for New Mexico Medicaid

The New Mexico Health Care Authority (HCA) and its Income Support Division offices handle Medicaid eligibility determinations. Per the HCA Turquoise Care FAQ, applications go through the YesNM portal, by phone, or in person at an Income Support Division (ISD) office.

What you need to apply

HCA verifies identity, New Mexico residency, income, household size, and citizenship or immigration status. MAGI-based groups (most adults, children, pregnant women) have no asset test — savings, vehicles, and home equity are not counted.

• Full legal name and date of birth for each household member applying
• Social Security numbers for all applicants
• Proof of New Mexico residency — utility bill, lease, or official mail at current address
• Income documentation — pay stubs from the past 30 days, employer letter, or last year's tax return
• Immigration documents for non-citizen applicants
• For institutional care (nursing home) applications: contact HCA directly — non-MAGI rules apply and an asset review is required
• For Native Americans: tribal enrollment documentation if you wish to opt out of managed care

Selecting a Turquoise Care health plan after approval

Once approved for Medicaid, most members are enrolled in Turquoise Care managed care. Per the HCA, four MCOs serve the Turquoise Care population: Blue Cross Blue Shield of New Mexico (BCBSNM), Molina Healthcare of New Mexico, Presbyterian Health Plan, and United Healthcare Community Plan of New Mexico. Each plan offers different Value-Added Services beyond standard Medicaid benefits — a list is available at hca.nm.gov.

Select your MCO through the YesNM portal or by calling 1-888-997-2583. If you do not choose a plan, HCA will assign you to one. You can change plans within the first 90 days of enrollment, and then once annually. Ask your current doctors whether they are contracted with a given MCO before selecting — especially in rural areas where network differences matter most.

Under 42 CFR 435.912, HCA must process most applications within 45 days. Coverage typically begins the first of the application month if approved. Pregnant women may receive retroactive coverage going back up to three months.

What documents you'll need

Gather these before starting your application. Having them ready prevents delays caused by missing information requests, which can add weeks to the review.

• Proof of identity — driver's license, state ID, passport, or birth certificate
• Proof of residency in New Mexico — utility bill, lease, or official mail with your address
• Social Security numbers for all household members applying
• Proof of income for the past 30 days — pay stubs, employer letter, or benefit award letters
• Tax filing information if self-employed — prior year return is typically acceptable
• Immigration documents if applicable — green card, visa, or I-94 arrival/departure record
• Health insurance information if you currently have coverage through an employer or other source

Not every document is required for every applicant. The application will specify what New Mexico Medicaid needs based on your household composition.

The application process, step by step

1. 1

   Gather your documents

   Collect proof of identity, residency, income, and household composition before you start. Having everything ready means you can complete the application in one sitting.

2. 2

   Submit the application

   Apply through your preferred method — online is fastest. The application asks about income, household size, citizenship status, and whether anyone in the household has other insurance. Answer completely to avoid requests for more information.

3. 3

   Respond to any follow-up requests

   New Mexico Medicaid may request additional documents or clarification. Respond promptly — delays in providing information can pause or restart the review clock.

4. 4

   Receive your eligibility notice

   The agency will send a written notice of approval or denial. If approved, the notice will state your coverage start date and what benefits you're eligible for.

What to expect after you apply

Under 42 CFR 435.912, states must process most Medicaid applications within 45 days of receipt. Applications based on disability take up to 90 days. If New Mexico hasn't issued a decision by those deadlines, the agency must notify you in writing with the reason for delay.

Medicaid coverage typically starts on the first day of the month in which you applied, assuming you're determined eligible. In some cases — particularly for pregnant women — retroactive coverage going back up to three months may apply if you received qualifying medical services during that period.

Keep your contact information updated while your application is pending. A notice sent to an old address counts as received.

If your application is denied

A denial notice must state the specific reason and your right to appeal. You have the right to request a fair hearing — typically within 90 days of the denial notice — where you can present evidence and contest the decision before an impartial hearing officer.

Common denial reasons include income above the limit, failure to verify documents within the required timeframe, or a missing signature. Many denials can be resolved by reapplying with the correct documentation.
